Thanks Mario, The only problem with those is that we need 28 IO ports. It would be easy enough (for me, the software guy) to just use two of them but now the board is layed out and there would be resistane to changing it if we could just find the right part somewhere. It may be that we end up having to use these parts and just redo the board. I saw on the CCS compiler site example code for the MAX7300. Thats another thing that would make me think it would be more available, but alas... still looking.
